Pop idol Justin Bieber gazes dreamily at a pretty Brazilian teenager he is said to have become `besotted with` after meeting her in a nightclub - `because she looked like his ex, Selena Gomez`.

The Canadian heart-throb reportedly told staff at the Zax Club he wanted to take the girl back to his rented Rio de Janeiro mansion because `she looks just like Selena`.

Biber picked the girls who would be allowed into the VIP area individually, according to the manager. And, despite inviting 30 girls back for a private party, he hardly left 18-year-old Fernanda Paes` side, even leaving the club with the girl underneath the same blanket as him.

It`s claimed he chose Paes above all the other girls in the club because she bore an uncanny resemblance to Bieber`s ex Selena Gomez
